An optical writing device includes an integral structure of a plurality of light emission device array units securely connected together, the units including respective lines of light emission devices, the lines being formed into a longer line of light emission devices on the integral structure, a position fixing member, and a connection mechanism that fixes the integral unit to the position fixing member only at a single connection point such that displacement of the integral unit relative to the position fixing member in a direction of the longer line is prevented only at the single connection point but unrestricted at any other points.
